Application filed May 11, 1914. Serial No. 837,666.

To all whom it may concern Be it known that I, HERBERT B. SPERRY, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin sheaf-Carriers, of which the following is a full, clear, and exactspecification.

My invention relates to sheaf carriers, and in particular to meansoperatively connected with the power transmitting mechanism of aharvester and its sheaf carrier in a manner to cause the carried to dumpits load at predetermined intervals controlled by the distance of travelof the machine.

The object of the invention is to provide means for automaticallyactuating the carrier in a manner to dump an accumulated load and toreturn the carrier to its sheaf receiving position regardless of thenumber of sheaves received, and manually controlled means operative tosuspend the automatic action of the carrier controlling mechanism or tocause it to dump its load at any instant, at the will of the operator.These objects are attained by means of mechanism one embodiment of whichis illustrated in the accompanying drawings, in which- Figure l is a topplan view of a sheaf carrier and part of a harvester having the carrierattached thereto and having my invention forming a part thereof; Fig. 2is a detached detail of part of the automatic mechanism for operatingthe carrier; Figf3 is a view in perspective of an assemblage of parts ofthe carrier operating mechanism; Fig. 4: is a vertical cross section onan enlarged scale of Fig. 3 along line AB; Fig. 5 is a cross section ofFig. 3 along line CD; Fig. 6 is a view similar to Fig. 5 and designed toillustrate the operation of part of the sheaf carrier actuatingmechanism; Fig. 7 isa side elevation, partly in section, designed toillustrate the manner of connecting the sheaf carrier actuatingmechanism with an operative part of a harvester; Fig. 8 is an endelevation'of a'worm wheel and sleeve forming part of the carrieractuating mechanism as shown in Fig. 3; Fig.

9 is a bottom plan view of Fig. 8; Fig. 10 is a side elevation of a pawlcarrying wheel forming part of Fig. 3; Fig. 11 is a bot m view of Fig.10; Fig. 12 is a side elevation of a ratchet wheel forming part of Fig.3; Fig. 13 is a bottom view of Fig. 12; Fig. 14 is a side elevation of atoothed set wheel designed to control the periodicity of the operationof the carrier dumping mecha-' nism; Fig. 15 is a bottom view of Fig.14; Fig. 16 is a plan view of part of the setting mechanism cooperatingwith the set wheel, as shown by dotted lines in Fig- 4; and Fig. 17 is aside view of Fig. 16.

Referring to the drawings, wherein the same reference numerals designatelike parts throughout the several views, the wheel frame of theharvester is represented by 1, and includes longitudinally disposedframe members 2 and 3 upon the stubbleward' and grainward sides,respectively, of the traction wheel 4., 5 the rear frame member, and 6the seat supporting pipe.

7 represents a cross shaft journaled in bearings carried by the wheelframe in rear of the traction wheel, and operatively connected with thetraction wheel by means of sprocket wheels 8 and 9 carried by the crossshaftand traction wheel, respectively, and the sprocket chain 10.

11 represents the harvester crank shaft journaled in bearings carried bythe wheel frame 1 upon the stubbleward side of the traction wheel, andhaving a pinion 12 secured thereto that meshes with a bevel gear wheel13 secured to the cross shaft 7 14 represents a gear carrying bracketsecured to the wheel frame member 2 by means of a U-shaped clampingmember 16 andhaving transversely disposed sleeves 17 and 18 integraltherewith at the front and rear ends thereof, respectively. I

Secured to the crank shaft 11 is a worm carrying sleeve 19, preferablymade in two parts, whereby it may be conveniently secured to the shaft11 by means of bolts 20,

and having separate worms 21 and 22 at the front and rear ends thereof,respectively.

23 represents a worm wheel operatively engaging the worm 21, and havingintegral therewith a sleeve 24 journaled in the sleeve 17, and 25represents a ratchet toothed wheel secured to theend of the sleeve,preferably by a threaded connection. I

1 26 represents a s aft journaled in the sleeve 24 and having auniversal coupling member 27 secured to its stubbleward end. Secured tothe shaft 26 is a wheel 28, having a laterally extending peripheral rim29 provided with a gap 30, and 31 represents a pawl member pivotallymounted'upon the wheel 28 eccentric to its axis, and having a peripherallaterally extending rim 32 provided with a radially extending tooth 33.The pawl member 31 is in the form of a ring, and its radial web isslidably received by a laterally extending hook member 34 integral withthe wheel 28 and preferably located within the gap 30. The web of thepawl member is provided with a gap 35, the end walls of which areadapted to engage with the hook member 34 in a manner to limit aswinging movement of the pawl member in opposite directions. The pawlmember 31 is adapted to swing about its axis in a direction to cause aninwardly extending tooth 31 integral therewith to engage with theratchet wheel 25, or to be disengaged therefrom. A curved spring 35having one end connected with the pawl and its opposite end with thewheel 28, is operative in a manner to normally throw the pawl inengagement with the ratchet toothed wheel 25. Loosely mounted upon theshaft- 26, upon the opposite side of the wheel 28, is a toothed wheel,36, having a laterally extending wing 37 that overlaps the rim 29 ofwheel 28 and contacts with a laterally extending stop member 38 integralwith a crown toothed set member 39 loosely mounted upon the shaft 26,and 40 represents a vertically disposed bar having an openingintermediate its ends that receives the end of the shaft 26, the lowerend of the bar engaging with a laterally extending plate member 40secured to the lower side of the bracket mem ber 14 in a manner tosecure it against a turning movement upon the shaft, and its oppositeend turned laterally and provided with an opening that receives a pin 41that engages with the teeth of the set wheel member 39 in a manner tosecure the set member in any desired position of angular adjustment uponthe shaft 26.

42 represents a torsional spring coiled around the hub 43 of the toothedwheel 36, having one end secured to said wheel and its opposite endpassed through a semicircular concentric slot 44 in the set member 39and secured to the bar 40, the spring being operative to turn the wheel36 in a direction to cause the wing 37 to engage with the stop sleeve 18and having secured to its opposite end an eccentric 47, and48 representsa reciprocating pawl member having one end mounted upon the eccentricand its opposite free end adapted to successively engage with the teethuponthe Wheel 36 as the shaft 46 rotates.

49 represents a gravity dog having an opening at one end that looselyreceives the extended end of the shaft 46, and the opposite free end ofthe dog is adapted to engage the teeth of the wheel 36 in a manner tonormally prevent a rotative movement of the wheel in a directionopposite that as actuated by the reciprocating pawl 48.

50 represents a latch member having one end loosely mounted upon theshaft 46, upon the opposite side of the eccentric 47, and

its opposite end provided with a hook 51 that engages with the radialtooth 33 of the pawl member 31 in a manner to normally hold the pawlfrom engaging with he ratchet toothed wheel Secured to the shaft 26,adjacent the worm wheel 23, is a scroll cam member 52, with which aroller 53 engages, the roller being journaled upon one end of a rod 54,slidably mounted in bearing members 56 secured to a bracket 55 carriedby the extend- 7 ed ends of the shafts 26 and 46.

57 represents a coiled compression spring encircling the rod 54 andoperative between a pin 58 through the rod and one of the bearings 56 ina manner to yieldingly hold the roller 53 in contact with the scroll cam52, the cam being provided with a radially disposed shoulder 59 withwhich the roller engages in a manner to prevent a rotative movement ofthe cam in one direction.

60 represents a sheaf carrier supported by the wheel frame 1, andincluding swinging fingers 61, supported by a bar 62 and controlled by alongitudinally movable bar 63 ina well-known way to cause the fingers toswing rearwardly and downwardly to a folded and trailing position uponthe ground in dumping an accumulated load, and to be returned to anoperative position to receive the sheaves. For the purpose of actuatingthe carrier automatically I provide a link member 64, having one endconnected with the bar 63 and its opposite end with a crank arm' 65integral with a shaft 66 journaled upon a fixed part of the carriersupporting mechanism, and operatively connected with the universalcoupling member 27. When the carrier is in a sheaf receiving positionthe roller 53 is in engagement with the shoulder 59 of the scroll cammember 52 and thereby retains the carrier in its receiving position,whereas otherwise the weight of the accumulated load would cause thecarrier to 'be-moved toward its dumping posi tion.

In operation the crank shaft 11 of the worms 21 and 22 secured thereto,imparts continuous rotative movement to the worm wheel 23 and theratchet toothed wheel 25 secured to the sleeve 24 and to the worm wheel45, the shaft 46 and the eccentric 47.

The rotative movement of the eccentric 47 imparts a reciprocatorymovement to the pawl member 48 that successively engages with the teethof the wheel 36 and thereby imparts a step by step rotative movementthereto against the tension of the spring 42, and the gravity dog 49engages successively with the teeth as the wheel is turned and preventsa return movement thereof as the pawl 48 reciprocates, the wheelcarrying around with it the wing member 37. When the wing 37 passes theposition shown in Fig. 5 it disengages the latch member 50 from thetooth 33 of the pawl member 31, as shown in Fig. 6, and the spring 35swings the pawl into engagement with the ratchet toothed wheel 25 andthereby a rotative movement is imparted to the shafts 26 and 66. Thecrank arm and the link connection 64 to the controlling bar 63 of thesheaf carrier move the bar in a direction to dump the accumulated load,and then in a direction to return the carrier to its sheaf receivingposition. The end wall of the gap 35 of the pawl member 31 engages withthe hook member 34 of the wheel 28 and carries the gap 3() beyond thepath of movement of the pawl 48, and the gravity dog 49 and the rim 29at the end of the gap lifts the pawl 48 and dog 49 to a plane preventingtheir engagement with the toothed wheel 36, and when the pawl and dogare released the spring 42 immediately returns the wheel 36 to itsoriginal position with the wing 37 contacting with the stop member 38upon the set member 39 at the end of the cycle of movement of thedumping mechanism.

The set member 39 is designed to be adjustable angularly to vary theintermittent action of the carrier dumping mechanism according to thedistance traveled by the harvester and the desired distance apart of therows of dumped sheaves, the mechanism being operative to maintain therows of discharged sheaves in such parallel relation regardless of thenumber dropped by the carrier controlling mechanism at each cycle of itsmovement.

In the operation of the device it is desirable that means be providedwhereby the automatic action of the mechanism may be temporarilysuspended at the will of the operator, as when the machine would beturning at the corners of the field and the row would be in the path ofthe team or other propelling means, and it would be necessary to carrythe load beyond one row and dump it at the next and to permit themechanism to resume its automatic operation when such suspending meanswas released. The means provided for attaining this result include afoot treadle 67 pivotally mounted upon the seat supporting member 6 andhaving a laterally extending'crank arm 68 pivotally connected with thefront end of a link 69, the

rear end of said link being pivotally connected with a crank arm 70integral with one end of a diagonally disposed crank shaft 71 journaledupon the frame of the har vester, its rear end in a bearing 72 and itsfront end in a bearing 73 and provided with a crank portion 74 near itsopposite end that is connected with the front end of the gravity dog 49by means of a link 75. When the operator manipulates the foot treadleand rocks the shaft to a position shown by dotted lines in Fig. 1, thelink 75 swings the gravity dog 49 about its axis and disengages it fromthe toothed wheel 36, and while it is held disengaged the pawl 48 willnot successively engage the teeth upon the wheel 36 in a manner toadvance it, andv consequently the cycle of operative. operation of theautomatic mechanism is suspended until the operator releases the foottreadle and permits the torsional spring 76, carried by the shaft andoperative between a fixed part of the frame structure and the shaft, toturn it to its initial position. Means are also provided whereby theoperator may cause the mechanism to operate to dump a loadfrom thecarrier at will, comprising a pawl arm 77 integral with the front end.of the rock shaft 71 and disposed beyond the bearing 73.

78 represents a link slidably received by an opening in a fixed part 79of the frame structure, having one end pivotally connected with the freeend of the latch member 50 and its opposite end provided with a notch 80adapted to be engaged by the front end of the pawl arm 77 when the shaft71 is released by the operator and permit it, under the torsional forceof the spring 7 6," to return to its normal position, the pawl becomingdisengaged from the notch when the shaft has been given a predeterminedde gree of angular movement, as shown in Fig. 2. When the operatorswings the foot treadle forward the action; of the automatic mechanismis suspended, 1 and will remain suspended until the treadle is releasedand the rock shaft permitted to return to its normal position, and whilereturning itv trips the latch member 50 and the load is immediatelydumped and the automatic mechanism resumes its regular cycle ofoperation.

Having shown and described a preferred be confined to the specificdetails of construction as illustrated and described, it beingunderstood that many changes may be made both in the form and proportionof the parts Without departing from the spirit of my invention.
